POULTRY-DISINFECTOR-.

To all whom #may concern Be it known that I, GEORGE CARLSON, va

i in the county of New York and State of New partlysecti'ned and partly broken away.

York, have invented a certain new and useful Poultry-Disinfector, of w'hich the following is a specification, reference being had therein to the accompanying drawing.

This invention is a novel poultry disinfector, that is to say, an apparatus adapted to dust an insecticide powder, or to spray any other disinfectant upon live poultry. The principal object of the present invention is to afford such an apparatusv which will be wholly self-acting and requiring very little attention from the poultry keeper, and which as well will be simple in structure, effective in action and convenient of use. Other objects and advantages of the present invention will appear in the hereinafter following description or will be understood to those skilled in the art.

To the attainment of such Vobjects and advantages, the present invention consists in the novel poultry disinfec'tor and the de; scribed and illustrated features of combination, arrangement, mechanism and detail. The illustratedembodiment of the present invention discloses a compact and portable apparatus which can be placed where desired, for example, in the entrance to the hen-house or a runway, and'. as will be seen it is adapted to operate both directions,

that is, on poultrycoming and going so that they are sprayed at both front 'and rear. The apparatus perferably contains a boxlike structurefrom the front of which projects a balanced low platform across or upon which a hen may walk or hop in entering or leaving the hen-house. Within the casing are the pneumatic sprayer directed outwardly at the front, and the mechanism for operating and controlling the same.

ln the accompanying drawings illustrating one'embodiment of the invention, Figure 1 is a perspective view showing my disinfectin'g apparatus placed at the entranceof a hen-house.l i f n I y i Fig. 2 is 'aside elevatipnonlavlarger scale and with the earest of lsidewalls omitted to better disclose the"inter1or mechanism and operation.

Fig. 3 is a top v1ew on large scale, of the double vnozzle and its cleaning device.

Fig..4,is a left end view of the apparatus,

durable,

The box or casing of my invention com- .prises side walls 4, 4, a top wall 5 over which the poultry may walk, and preferably a bottom wall or base 6. A rear wall 7 is also shown, and an inclined plank 8 leads up. from the ground at. the rear to the top of ther box.A A front wall 9 may be added to protect the operative parts, and'this is shown as having a small flange orhood l0 over the opening through which the nozzle projects. The top wall 5 may be hinged at 11 to permit lifting -a/nd inspection.

The operating member of this invention is the balanced low platform or board 12 projecting forwardly, as indicated, and pivoted to the side walls of the frameat 13. The

and have shown two spray exits 16, 16, side by side and slightly diverging. vln order'tokeep the spray nozzles clean, 1 have provided a bent wire 17 whichl extends bodily through bothnozzles and at its outer end is hooked'at 18, 18 for connection to eyes 19, 19

y(of an operating wire '20 extending rear-A wardly and secured to a movable part of the board or extension 14. By this arrangement the wires are moved in the nozzles every time the a paratus is worked.

A hopper 21 iiaving anairtight coverl22 holds the disinfectant orA powder, which passes by a pinhole 23 into the pipe 24 which leads directly tohthe sprayer nozzle 16. A

\lap valve 25 ingthe pipe 24 permits air to iow toward but vnotfrom the nozzle.

The pneumatic mechanism comprises an operartm cylinder 26 constructed of a short length `o iron pipe and having fitted within it a piston 27 above which is the outlet 28 to vthe pipe 24 and nozzle. The cylinder .has a head 29 slightly Ibelow its top end, affording an extension 30 in which lare formed oppo. site holes through which passes a frame cross-bar 32 extending from sidewall. to sidewall of the apparatus, for supporting the cylinder. *A spring inlet valve 33 admits air. The piston is on the'piston down stroke.

operated by a rod 34 uidcd by a cross-piece 35 at the lower end of fthe cylinder, and the rod has a cross-head 36 the ends' of which are connected by links or rods 37 to the two sides of the yoked extremity of the boai'd or platform 14.

By this arrangement, when the hen jumps onv the front `part L?,v of the platform, the rear or interior end causes the piston 'to rise thus forcing air from the cylinder through the pipe 24:, so as to carry the powder from the Lhopper 21 to the nozzlel, whence it is sprayed upon the fowl.l 'When the air is under pressure part of'it will' p ss through the pinhole 23 into the hop vr thus stirring.

v up the disinfectant, and suc air forced into the hopper promptly returns thus insuring passage of a suitable amountof powder into the pipe 24 ,at each operation.

It will be noticed that the balanced plat.- form is pivoted to'fthe. frame of the apparatus, and that the pneumatic device is mounted on the frame and independent of the platform'although operated by the movements of 2.5 the latter. I am enabled to make the frame in the form of a hollow casin so combined with the platform that the fatter extendspartly outside and partl inside of the casing, the inside end and t e mechanism oper- 80 ated 'by it being protected by the casing. 'The `wliole device is very compact, and the compactness of theinterior parts is enhanced by the low location of the cylinder which is permitted b the use of the connecting. links extending rom` the piston cross-head upwardly to the extremity of the inside part of the balanced platform.

It will thus be seen that have vdescribed 'a novel poultry disinfector embodying the.

' i40 principles :and attaining the advantages of the present invention.

Since many matters of design,

arrangement, combination and de- .tail may be variously modified without dearti from the' underlying principles, no imitation thereto is intended except in so far as specified in the appended claims.
